Processes of phase instability in high-temperature steels subjected to long-term heating

The phase composition and properties of martensitic steels of the Fe-C-Cr-Ni-Co-Mo-W-Nb system are studied. The nature of phase instability in long-term heating in the temperature range of 450-600 deg C is determined. The effect of concentration and kinetic factors on the formation of Laves, alpha-C...

Zusammenfassung:The phase composition and properties of martensitic steels of the Fe-C-Cr-Ni-Co-Mo-W-Nb system are studied. The nature of phase instability in long-term heating in the temperature range of 450-600 deg C is determined. The effect of concentration and kinetic factors on the formation of Laves, alpha-Cr, and sigma-phases is considered. Recommendations are given on prevention of segregation of phases negatively influencing the impact toughness and corrosion resistance of the studied steels.
